Just fixed it in git, expect it to be part of the upcoming 1.0 release. The problem was that apt.Cache() had a cyclic reference to itself, because it stored its own methods in its callback dictionary. BTW: There is no need to open() the cache, the constructor already opens it. -- Julian Andres Klode - Debian Developer, Ubuntu Member See http://wiki.debian.org/JulianAndresKlode and http://jak-linux.org/.
